The relevance of irrelevant information
通过实验研究不可得选项和无关信息如何影响决策最优性,发现两者会共同导致次优决策,且无关信息增加决策时间成本,存在超越最优决策的“简单偏好”。
Abstract This paper experimentally investigates the effect of introducing unavailable alternatives and irrelevant information regarding the alternatives on the optimality of decisions in choice problems. We find that the presence of unavailable alternatives and irrelevant information generates suboptimal decisions with the interaction between the two amplifying this effect. Irrelevant information in any dimension increases the time costs of decisions. We also identify a “preference for simplicity” beyond the desire to make optimal decisions or minimize time spent on a decision problem.
